In these days of jaw-dropping trillion-dollar budgets and deficits along with current retirement obligations 7X the size of our economy, $6.3 billion may not sound like much. But, hey, a billion here and a billion there, and pretty soon you are talking about real money.
$6.3 billion what the United States potentially could save on each group of adolescents who enter foster care every year - and get better results.
It's not often in 2009 anyone, much less in academia, is discussing privatization of public services but new research led by economists and foster care experts from…
An indignant letter in this month's Chemistry World has drawn my attention to a forthcoming ban on the use of dichloromethane, except by the most professional of professionals. EU sidesteps Reach to ban paint stripping solvent goes the relevant article, Reach being an acronym for Registration, Evaluation and Authorisation of Chemicals.
Dichloromethane is indeed king of the paint strippers. As I learnt during a project to test these, it has the right solubility parameters (note the plural, I'm using the multi-dimensional approach) to go for most paint resins, and moreover its small molecular…

Which of the following Latin American countries has the highest murder rate?
a. Nicaraguab. Mexicoc. Venezuelad. Jamaica
If you answered "Mexico", you made a very reasonable choice. In the past year, violence has been so rampant there that murder numbers have often exceeded 100 per week. But Mexico does not have the worst problem in the region - that distinction goes to .... Venezuela. Venezuela's rate of 48 violent deaths per 100,000 people is double that of Mexico.
Now, if asked instead to name the top-spot for homicide in all South America, surely drug-crime-ravaged Columbia would come…
I’m fascinated by the contributions of researchers outside of the mainstream— the monk whose bean garden seeded modern genetics, the bicycle mechanic brothers who built a flying machine in their garage, and all of those amateur stargazers who found supernovae in their favorite corner of the sky.
Modern indie researchers, often called "grassroots scientists" or “citizen scientists”, make especially good food for thought when grad school is at its most frustrating. It’s comforting to remember that at its heart, science is still open to anyone with a bit of curiousity and good observation…
"Somebody's got to stand up to experts," cried the creationist head of the Texas State Board of Education, Don McLeroy. McLeroy's lament is nothing new in American culture - we love to lionize the artless hero who conquers the world through clean living and common sense, and without resorting to elitist expertise. (Although some see the pendulum swinging the other way.)
Technical prowess has been a key part of America's development from a colonial coastal settlement into a continent-spanning world power, yet ambivalence about science, technology, and professional expertise is been genetically…
Many parasites depend on their host’s behavior in order to successfully reproduce. Instead of leaving this behavior to chance, some parasites actively manipulate their hosts to produce the desired behavior. For example, after infecting a rat, the taxoplasmosa gondii parasite needs to be transferred to a cat’s belly to reproduce. To do this, the sneaky parasite rewires its rat host to actively seek the smell of cat urine. When the rat gets eaten, the parasite completes its necessary transfer.
Cordyceps fungi infect insects and steer them to higher ground where, when the insect dies and the…
If you watched "Angels&Demons" recently, you may have thought particle physics was just about scary science that could do real harm on the chance it may do future good.
Not so, though most people don't realize the impact particle physics has had on society. Particle physics saves lives, connects continents through new channels of communication and generally helps us understand the world around us. In many ways it inspires tomorrow’s leaders.
While the perils associated with particle physics, from Earth-gobbling black holes to Vatican-destroying amounts of antimatter,…
Brian Greene on science as the ultimate adventure:
Science is about immersing ourselves in piercing uncertainty while struggling with the deepest of mysteries. It is the ultimate adventure. Against staggering odds, a species that has walked upright for only a few million years is trying to unravel puzzles that are billions of years in the making. How did the universe begin? How was life initiated? How did consciousness emerge? Einstein captured it best when he wrote, "the years of anxious searching in the dark for a truth that one feels but cannot express." That's what science is about.
It's…

In general, science is like an episode of "LOST"; one question gets answered but that answer raises two more questions. The discovery of DNA and genes has answered many questions about who we are and why we are, but to what degree remains a mystery.
'Nature Versus Nurture' has been an argument for decades. Nature proponents state that genes are primarily responsible for everything, including our eventual personalities and behaviors, and that they can all be explained by certain sequences of DNA. The Nurture argument instead says that although genes and DNA play a part of our anatomy and…
U.S. Army Chemical Materials Agency (CMA) officials have announced the destruction of 60 percent of the U.S. declared stockpile under the Chemical Weapons Convention (CWC). This milestone was achieved Saturday, April 25. CMA reached the 50 percent milestone in December 2007 and is poised to destroy its two-millionth munition in the coming months.
"We have increased our efficiency at destroying the nation's chemical weapons stockpile while maintaining the highest safety and environmental compliance standards," said Conrad Whyne, CMA Director. "This accomplishment is the result of a true…
